Repeated output in simple for loop

Question

I've got the following list

ninjas = ['ryu', 'crystal', 'yoshi', 'ken']

I'm playing around with loops and have the following for loop

for ninja in ninjas:
    if ninja == 'ryu':
        print(f'{ninja} - black belt')
    if ninja == 'ken':
        print(f'{ninja} - brown belt')
    else:
        print(ninja)

The output I want is

ryu - black belt
crystal
yoshi
ken - brown belt

but the output I get is

ryu - black belt
ryu
crystal
yoshi
ken - brown belt

I'm assuming that after the first if statement it is looping back around to the start, hence the repeated 'ryu', how do I stop it doing that?

Thanks in advance

I'm assuming that after the first if statement it is looping back around to the start that is false, it continues to the next if statement which has an else condition. You need to nest your ifs — Yuca

To get what you actually expect you need:

for ninja in ninjas:
    if ninja == 'ryu':
        print(f'{ninja} - black belt')
    elif ninja == 'ken':
        print(f'{ninja} - brown belt')
    else:
        print(ninja)

Thank you, I had just figured out another way to do it seconds after you posted but yours is more concise so I much prefer it.
